Retained (old) foreign body in vitreous body, right eye

This code signifies the presence of a non-magnetic foreign object, which has been in the vitreous humor of the right eye for an extended period. This foreign body is not recent and is not attracted to a magnetic field, differentiating it from acute or magnetic foreign bodies.

Use this code when documentation clearly indicates a foreign body in the right vitreous that is explicitly described as "retained," "old," or "nonmagnetic." This typically applies to cases where the foreign object has been present for a significant duration, often discovered incidentally or during follow-up examinations.

• Ensure the documentation specifies "right eye" and "vitreous body" to avoid laterality or anatomical site errors.
• Distinguish between retained (old) and current (acute) foreign bodies; different codes apply for acute presentations.
• Verify the foreign body is nonmagnetic; if magnetic, a different code from the H44.6 series would be appropriate.
